I may not be the ultimate expert in this, but I'm sure you're heading towards the Distributed Transactions. In order to have them running, all the application service components need a common shared transaction id, and you have to make sure that every component is informed about the state of the transaction. It is asynchronous, so you'll require substantial prog skills.

Here are distributed transactions mentioned or discussed:

It would seem people try to avoid it as it is difficult. Maybe that's why you don't find much about.

Hope this helps a step forward :-)
